赛 30:21-22

主虽然以艰难给你当饼，

以困苦给你当水，

你的教师却不再隐藏；

你眼必看见你的教师。

你或向左或向右，

你必听见后边有声音说：“这是正路，要行在其间。

And though the Lord gives you the bread of adversity and the water of affliction, yet your Teacher will not hide Himself any more, but your eyes will constantly behold your Teacher.

And your ears will hear a word behind you, saying: This is the way; walk in it, when you turn to the right hand and when you turn to the left.
